WebInfrared (IR) spectroscopy is one of the most common spectroscopic techniques used by organic and inorganic chemists. Simply, it is the absorption measurement of different IR frequencies by a sample positioned in the path of an IR beam. The main goal of IR spectroscopic analysis is to determine the chemical functional groups in the sample.

WebIt's just that a spectrum is usually divided into a region where there are few absorptions (the diagnostic region) and a region where there are so many lines that it is difficult to say what causes them (the fingerprint region). It differs from one molecule to another but, for most molecules, the dividing line is usually around 1500 cm⁻¹.

"WebFor example, the most characteristic absorption band in the spectrum of 2-hexanone (Figure 6.3a) is that from the stretching vibration of carbonyl double bond C=O at 1716 cm-1. It is a very strong band comparing to the others on the spectrum. A strong absorbance band in the 1650–1750 cm-1 region indicates that a carbonyl group (C=O) is present. " - Ir spectrum breakdown
